EDWIN D. CASTERLINE, OF: SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO INTERLOCK PAPER COMPANY, OF SAN FRANCISCO, CALIFORNIA, A

CORPORATION OF CALIFORNIA.

RIBBON-PAPER FEEDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 787,662, dated April 18, 1905.

Appiicaion iiied August 29,1904. serai No. 222,563.

city and county of San Francisco and Stater of California, have invented new and useful Improvements in Ribbon-Paper Feeders and Cutters, of which the following is a specification.

My invention relates to improvements in devices for cutting strips of paper and other material into definite uniform lengths. It is designed especially for cutting cigarette-paper and to be used in conjunction with a folding-macliine of the type shown in Patent No.

654,515, issued July 24, 1900. Its object is to provide a simple, durable, automatic, rapid, and continuous machine for cutting any number of simultaneously-fed paper strips or ribbons into proper uniform lengths.

construction and combination of parts, as

hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a plan view of my device. Fig.

2 is an end view of same from right of Fig. 1. In carrying out my invention I employ in combination with a suitable support, as A,

two endless-band carriers or belts 2 3, having parallel portions between which the material to be cut is conveyed, these parallel portions being' supported against the adjacent faces of the adjustable guides 4.

Any suitable means of mounting and driving the belts 2 3 may be used. In the present instance I have shown each belt as passing around a sprocket 5 and two drums or pulleys 6, a drum being disposed proximate to each end of a respective guide 4, but so arranged as to allow either' guide to beinoved from or toward its neighbor to vary the space between the guides. The guides are slotted, as at 7, and this transverse adjustment is effected by suitable means, as the screws 8.

The driving of the belts simultaneously and in opposite directions is shown as effected through the medium of the intermeshing gears 9 10, having each a respective sprocket 5 fast The invention consists of the parts and the to it. Gear 9 has also a bevel -gear surface 11, meshing a pinion 12 on a shaft 18, j ournaled on the frame. Motion is transmitted to shaft 13 from drive-shaft 14 by the/interated by suitable means coordinating with the travel of the belts. so as to sever always a uniform length of material. This cutting device comprises a fixed knife member 16 and a movable member 17. The latter is pivoted at 18, and the two members are held in normal open position by means of the spring 19. The sudden closing of the members is effected by means' of a revolving cam 20, carried on shaft 14, engaging at each revolution a part, as 21, on the movable knife member 17.

In operation the guides 4 are adjusted to the thickness of the material to be cut. With cigarette-paper strips the distance between Athe guides, or rather the distance between the vadjacent surfaces of belts 2 3, would be approXimately equal to the thickness of a package of cigarette-papers, and the relative rate of travel of the belts to cam 2O would correspond to the length of the package. Compensation for any change in the tension of the belts by reason of the transverse adjustment of the guides is made by shifting the arbor of a pulley 6 of each belt in the slots 22. To maintain the ribbon-strips evenly in the guides, there is provided the transverselyslotted presser-plates 23 on the threaded studs 24. These presser-plates are regulated by thumb-nuts 25 to bear always on the edges of the strips.

As the shaft 14 may be operated continuously, so long as the supply of paper ribbons continues it is seen that the feeding operation of the beltsto the cutter is continuous.

The paper cut into suitable package lengths is delivered upon suitable carrier means to be delivered thence as desired.

As Vhere shown, there is a delivery-carrier 26, operated in unison With the feeding and der side of the base A and carrying a gear meshing a corresponding gear 29 on a counter-shaft. The latter carries a gear engaging' another gear on the shaft of a pinion 30, which meshes the gear 10.

The belts 2 3 are preferably perforated metal bands, and as they are subject to considerable tension and wear and are liable to be torn by the teeth of sprocket-wheels 5 each belt may be reinforced on its under side and adjacent to the edge receiving' the greatest strain from the sprocket-teeth with the transverse bars, strips, or thicknesses 3l.

It is obvious that various mechanical changes may be made in the present machine as here shown and describcd without departing from the principle of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A mechanism for feeding and cutting strips of material into uniform lengths comprising two endless carriers having parallel opposed coperating conveying-surfaces, means comprising two opposed parallel adjustablymounted guides for varying the distance between said surfaces, and a cutting device arranged in, and operating transversely across the path of the material conveyed by said carriers.

2. A mechanism for feeding and cutting strips of material into uniform lengths comprising two endless carriers having parallel opposed coper'ating conveying-surfaces, means comprising two opposed parallel adjustablymounted guides for varying the distance between said surfaces, a cutting device arranged in the path of the material conveyed by said carriers, and means for operating said device cordinately with the movement of said carriers and in a plane substantially at right angles to the travel of the strips.

3. The combination of two opposed parallel transversely-adjustable guides, endless carriers having each a plane supported by a respective guide, means for operating-said carriers simultaneously and oppositely, and a transversely-operating cutting' device relative to the interspace between said guides.

4. The combination of two opposed parallel transversely-adjustable guides, endless carriers having each a plane supported by a respective guide, means for operating said carriers simultaneously and oppositely, a transversely-operating cutting device relative to the interspace between said guides and means for operating said cutting device and carriers cordinately.

5. The combination of two opposed parallel, adjustable guides, endless carriers having each a plane supported by a respective guide,means for operating said carriers, and transverselyoperating cutting means in the path of material conveyed by said carriers.

6. The combination of two opposed parallel,

adjustable guides. endless carriers having each a plane supported by a respective guide, means for operating said carriers, transversely-operating cutting means in the path of material conveyed by said carriers and means for operating said carriers continuously and for 0perating said cutting device cordinately with the carriers.

7. The combination of two cooperating endless carriers, having each a plane arranged parallel to a plane of the other, means comprising two opposed parallel adjustably-mounted guides for effecting an adj ustinent of said planes to vary their interspace, means for operating the carriers, and a transversely-operating cutting device in the path of the material conveyed by said planes.

8. The combination of two cooperating endless carriers, having each a plane arranged parallel to a plane of the other, means comprising two opposed parallel adjustably-mounted guides for effecting an adjustment of said planes to vary their interspace, means for operating the carriers, a transversely-operating cutting device in the path of the material conveyed by said planes and means for operating said cutting device cordinately with the carriers.

9. The combination of two coperatingendless carriers, having each a plane arranged parallel to a plane of the other, means, including adjustable longitudinal guides, for varying the space between said planes, other guides carried by the first-named guides and bridging said interspace, and a transverselyoperating cutting device associated with the carriers.

10. The combination of two cooperating endless carriers, having each a plane arranged parallel to a plane of the other, means, including adjustable longitudinal guides, for varying the space between said planes, other guides carried by the first-named guides and bridging said interspace, a transversely-operating cutting device associated with the carriers and means for operating the cutting device and carriers cordinately.

ll. The combination with a suitable support, of two cooperating endless carriers having parallel opposed conveying surfaces, sprockets on which said carriers travel, guidepulleys for the carriers and guides for directing the carriers into cooperative relation, said guide-pulleys and guides being adjustable, and a transversely-operatii'ig cutting device in the path of material conveyed by said carriers.

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
